ARTIFICIAL LEG PATENT
February 10, 1863 - U.S. Patent
Dubois D. Parmelee was issued a U.S. patent for an "Improvement in Artificial Legs" using a custom-moulded suction cup to receive the stump (No. 37,637). Atmospheric pressure held the socket in place such that "straps usually employed for this purpose can be dispended with, and at the same time a perfect fit of the bucket is attained." On the underside of the bucket "a small faucet" was open as the stump was forced into the tightly fitting socket. The faucet was then closed, and atmospheric pressure held the bucket in place until air is readmitted through the faucet. It was 90 years before his idea received general acceptance. Parmelee also invented the first key-operated adding machine (Pat. No. 7,074, 5 Feb 1850).

about Stolen On New Year's
More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)

about Eyesight Myth and Fact
Myth: Staring at a computer screen all day is harmful to the eyes.
Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them. Make sure lighting doesn't create a glare on your screen. When spending long periods at your keyboard, take a break now and then to rest your eyes to reduce fatigue. Also, don't forget to blink. Your eyes need to stay lubricated to feel comfortable.
